Description Peter W 2002-08-02 21:46:15 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020513

Description of problem:
The file /usr/src/linux-2.4/include/linux/iobuf.h has been changed between
2.4.18-3 and 2.4.18-5 and one of the members of the struct kiobuf (map_array)
has been removed (look at both files near line 53).  Since it hasn't been
removed from the linux 2.4.19 I assume this was a mistake.  It has also been
removed from linux-2.4/fs/iobuf.c.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Install RedHat 7.3.
2.Use up2date to upgrade to kernel 2.4.18-5 (from default 2.4.18-3).
3.Notice that "map_array" is gone from
/usr/src/linux-2.4.18-5/include/linux/iobuf.h. (it *was* in corresponding
2.4.18-3 file).
	

Actual Results:  map_array is gone.

Expected Results:  map_array should not be gone.

the recoding of the kiobuff is actually a performance enhancement (the kiobufs
become leaner and use less memory/cache)
